IPC: B23Q7/00
Filed: 1941-12-19
Abstract: 555,605. Feeding sheets. MULLER & CIE MASCHINENFABRIK UND EISENGIESSEREI AKT.-GES., A. Dec. 19, 1941, No. 16413. Convention date, Feb. 27. [Class 100 (i)] In a machine for cutting or otherwise operating on blanks such as veneers the blanks are placed in register on a movable work table while this is in a position removed from the working position and the blank is held to the table by suction or positive gripping action while it is returned to operative position. The machine preferably is constructed with a feed or service table consisting of a series of hollow bars 48, Fig. 3, secured to a machine frame at intervals and provided with apertures 50 which are connected to a source of suction. The blanks are placed by hand against registering marks or gauges associated with the bars 48, and they are taken from the service table by a reciprocating work table consisting of hollow bars 57 secured to a carriage 56 which reciprocates on guides 63 adapted to be raised and lowered by means of a pair of levers 66 connected by a link 67 and operated by a cam on a shaft 80, the carriage being reciprocated by an oscillating lever 74 operated by a crankshaft 76. As shown in Fig. 3 one blank 146 has been registered on the bars 48 and a further blank 145 is shown in the position after its front edge has been operated upon by cutting- knives 1, 2 which together with a work clamp 29 and a fixed presser table 53 are constructed and operated as described in Specification 555,572, [Group VIII]. The blank 145 is held by suction to the bars 57, and after the blank is cut the carriage 56 returns towards the left, and the cut blank is stripped by an inclined fixed ledge 148. The bars 57 are moved to a position under the blank 146 and are then raised to detach the registered blank 146. The cutting-knives are operated by lever mechanism from a crank shaft 25, Fig. 6, which is driven by worm mechanism and a one-revolution clutch as described in Specification 555,572, [Group VIII], which comprises a pawl 97 and lever 100, Fig. 6, for controlling the pin 94 of the clutch. The shaft 106 which drives the mechanism for operating the carriage 56 and associated parts is operated by a similar one-revolution clutch with a pawl 119 controlled by a lever 121, and interconnected trip mechanism shown in Fig. 6 is provided so as to permit the one-revolution clutches to operate alternately. In a modification, Fig. 10, which is especially applicable for dealing with a small bundle 194 of veneers at a time, the bundle is secured to the service table by a rising-and-falling gripper 190, and to the moving table by means of a clamp 170 which is shown as gripping a bundle 193 in operative position, and in dotted lines in the position just before it moves into contact with the bundle. The gripper 190 is operated by a lever 183 in a manner similar to the operation of the carriage 56, and other mechanism is as described for the first modification.

Abstract: 789,751. Grass &c. cutting and drying food for animals. FELBER, N. June 10, 1955 [June 12, 1954], No. 16743/55. Classes 5(1) and 5(2). [Also in Group II] Vegetable material, e.g., grass for drying or silage, is first compressed into a compact mass at a restricted nozzle D2 by a screw conveyer D7 or between rollers or converging belt conveyers and is then cut into flakes by rotated oblique milling cutters E1 to 5, Fig. 1 (not shown), so that more surfaces are exposed to drying in the dryer G. The grass from a waggon load A is pushed on to a belt elevator B where its depth is equalized by a plate B1, the grass falling into a centrifugal separator C with rotating radial vanes Cl whereby heavier foreign material is thrown out past the grass receiving funnel D3 into a distant container H, Fig. 1 (not shown). The cut grass is passed by a belt conveyer F to the dryer G. In Fig. 3 the grass is tipped on to a grid conveyer 1 through a part of which passes exhaust hot air from the final drier. Such hot air blows the grass up against another grid conveyer 2, or a grid only, leaving any stones behind which are scraped off the conveyer by an inclined catcher plate 5. When beyond the air channel 3 the grass then falls down to the lower conveyer 4 and then passes to the main drier. To preserve the silage added beetroot, fruit or other sugar-containing matter may be dropped through a funnel direct to the cutters.

Title: Improvements in fuel supply arrangements for internal combustion engines
IPC: F02M59/10
Filed: 1926-07-05
Abstract: 278,423. Salmon, P. July 5, 1926. Actuating by air pressure. -In a fuel injector for a spontaneous ignition engine comprising a pump and a fuel injection valve within the pump plunger, the latter is operated directly by the pressure in the engine cylinder and injects the fuel on its inward stroke. The fuel is injected through a valve 22 by a hollow plunger 2 to which are secured pistons 10. 11 working in cylinders 8 9 in open communication with the engine cylinder 7 by the pipe 12. To equalize the total pressures due to combustion and compression the cylinder 8 is cut off by a shoulder 13 on the piston-rod at the end of the engine compression stroke and the gases above the piston 10 are released through the port 14. The cylinders 8, 9, have drains 15, 16. Fuel is supplied to the pump-barrel 3 by a pump on the engine through a non-return valve 50, and fuel from the latter pump may be supplied by the port 16 to the cylinder 9 to assist in returning the plunger 2. The plunger stroke is varied by adjusting through gearing 20 the position of a nut 18 which acts as a stop to a collar 19 on the plunger. The valve is actuated by a, cam 27 and spring 25 through the lever 24. An air-release valve is provided at 17 for use when priming the pump. In a modification, Fig. 2, one piston 11 only is used and the valve 22 is opened by the pressure of the fuel acting on a shoulder 28 of its stem against the action of a spring 29 enclosed in a casing 30 secured to the plunger-stroke adjusting nut 18. When the nut is adjusted for a shorter stroke the compression of the spring 29 is lessened. The spring may also be adjusted by a screw 32.
